1.0 Introduction
The BinMaster Model C-100MB is a compact control console for a network of BinMaster SmartBob
sensors. It can control from 1 to 120 SmartBob sensors with a few keystrokes or automatically by use of
an interval timer or external start input signal. It has a 4-20mA current output that, in conjunction with the
external start input, provides for a traditional interface to a PLC (programmable logic controller) or DCS
(distributed control system) system. The console was designed with a NEMA 4X rating, thus if it is
properly installed it will be protected from windblown dust and rain. Vessel configuration is quick and
easy with a simple and intuitive user-interface, configurable in either the English or Spanish languages.
Measurement formats can be displayed as headroom percentage, headroom height, headroom weight,
product percentage, product height and product weight. Vessel configuration and user settings are stored
in non-volatile memory and will be retained during a power failure.
The Model C-100MB can be remotely accessed via a Modbus slave interface. Through the Modbus
interface, a Modbus master can initiate measurements, monitor measurement progress and retrieve
results for any or all SmartBobs enabled in the C-100MB console. For more information on the Modbus
interface, contact one of BinMaster’s application specialists. For further documentation, go to

2.0 Specifications
Power Requirements
Isolated 24VDC source with 5W (0.2A) minimum output or an isolated 16–24VAC source at
50/60Hz with 0.3A minimum output. The voltage at this input should not exceed 26.0 VRMS.
A quality earth connection is also required on the power terminal. Although this is not needed for
power or normal operations, it is required for proper protection from lightning and other electrical
surges.
SB-485 Port
RS-485 at 2400 bps using BinMaster’s proprietary half duplex protocol A or B and supporting 1 to
120 SmartBob sensors on up to 4,000 feet of a quality twisted-pair shielded cable.
EX-485 Port
RS-485 at 2400, 4800, 9600 or 19,200 bps using either Modbus/RTU (8E1, 8O1, 8N2) or
Modbus/ASCII (7E1, 7O1, 7N2).
Maintenance Connection
RS-232 using various speeds and protocols for Flash updates and maintenance.
External Start Input
Continuous monitoring for a dry contact closure to initiate a measurement with a response time of
less than 1 sec.
4-20mA Current Output
Continuous 4 – 20mA current output with 16 bits of resolution into a maximum load resistance of
560Ω. If weight calculations are DISABLED, the output level is relative to the last measurement
of a user-assigned vessel and its entered height. If weight calculations are ENABLED, the output
level is relative to the calculated weight of a user-assigned vessel and all its entered parameters.
An error condition (did not drop, bob stuck or communications error) can also be presented at this
output with a user-selectable value of either 2mA or 22mA.
